Cabon coated LiFe_0.5Co_0.5PO₄ solid solution (LiFe_0.5Co_0.5PO₄/C, LFCP/C) were synthesized via a facile rheological phase method using iron phosphate tetrahydrate (FePO₄·4H₂O) and iron oxalate dihydrate (FeC₂O₄·2H₂O) as iron source, respectively. The phase composition, particle morphology and electrochemical performance for the as-prepared materials were characterized by methods including X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM) and galvanostatic charge-discharge measurements. Results demonstrate that both LFCP/C samples possess olivine structure with high crystallinity, while there are significant difference in particle size distribution, carbon coating effect and electrochemical properties. As cathode for lithium ion batteries (LIBs), the LFCP/C obtained by FeC₂O₄·2H₂O as reactant exhibits better electrochemical performance than that by FePO₄·4H₂O, delivering a specific discharge capacity of 137.5 mAh·g^-1 at 0.1C (1C=150 mA·g^-1) rate in the voltage range of 2.5~5.0 V, and even at 10C rate, a specific capacity of 57.6 mAh·g^-1 is still maintained. Meanwhile, it shows excellent cyclability with a capacity retention rate of 78.1% after 100 cycles at 0.5C. The better electrochemical performance of LFCP/C obtained by FeC₂O₄·2H₂O can be mainly ascribed to its smaller average particle size, higher BET specific surface area, and more appealing carbon coating effect.
